Hmmm, so it gets deeper. I'm talking about a welder where the electrode does not get consumed. I guess GTAW or something. What does constant current get you as opposed to constant voltage?
Al_The_Man, if I got this right, because the stick needs constant current, they are regulating voltage to keep current at the same set level??
